To further increase the relevancy of search results, Li suggested that Google could in the future include RSS feeds to which users would subscribe, as well as bookmarked sites to get an idea of their interests.

The search engine could also look at the time lapse between when a user clicks on a search result and closes the page. This would allow the service to assess whether a result has been successful by tracking the length of time that a user spends on the page.

To deal with privacy concerns, Google requires users to sign in before they can use the service. They can also delete past searches from the search engine's memory or pause the recording feature.

Web users who currently subscribe to Gmail, Google Groups, Google Alerts or Froogle Shopping Lists can activate the feature by using their existing log-in and password.
